ELECTRIC-WIRE IMBEDDER.

Specification of Letters Patent.

Patented July 17, 1917.

Application filed January 10, 1917. Serial No. 141,723.

To all whom t mcg/uovwcrn':

Beit known that I, FRED lV. LUE'BECK, a citizen of the United States, and a resident of Knox, in the county of Starke and State of Indiana, have 'invented a new and Improved Electric-fire Imbedder, of which the following is a full, clear, and exact description. i

My invention relatesparticularly to a device for use in imbedding in the wax foundation of abee comb 'the wires of the supporting frame of said comb.' Itis the'practice to send an electric current through the wires to 'heat the same and cause them to melt their way into the foundation'. 'lVith devices as ordinarily lconstructe'd, theV Vfull length of a' wire is heated and this requires considerable time and considerable electric current. Y l

An object of my invention is to provide an imbedding device, whereby the current will be directed successively through short sections of the wire thereby requiring a small current, the device serving to heat the complete wire step by step along its length and arranged to exert a slight pressure on the wire to assist in imbedding the same as theheated wire melts the wax of the foundation.

A more speciic object of the invention is to provide an imbedding device of exceedingly simple construction and one that may be manipulated and controlled with facility and despatch, and whereby the time required to heat and imbed the wire will be minimized.

Reference is to be had to the accompanying drawings forming a part of this speciication in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a side elevation of an imbedding device embodying my invention, the foundation and its supporting frame being shown in section;

Fig. 2 is a plan view of the imbedding device; and

Fig. 3 is an enlarged cross section of the device in a plane corresponding with the line 3 3, Fig. 1.

In Fig. 1 the letter A indicates a frame and B the wires stretched between the sides of the frame to support the honey comb foundation C which in practice is formed of beeswax.

My improved wire imbedding device comprises a bar or like support 10. Extending longitudinally of the bar are spaced conductor strips 1l, the said bar being of insulating material or having an equivalent provision for insulating the respective strips. Secured to the bar 10 is a` series of contact elements 12 in the'form of'pins or the like, disposed perpendicular to a face of the bar and extending into the latter. The alternate Contact elements l2 are in metallic Contact with alternate strips l1. Moreover, it will be observed that the contact pins are of varying heights and advantageously, the variation is from the center pin toward the end pins, being gradually of increasing height Ifrom each end toward the center pin. The terminals 13 of the elements 12 are preferably iattened and brought to a tapered edge to make a good Contact with a wire B.

One terminal of each strip 11 has a binding post 141 or equivalent means to eii'ect connection with conductor wires 15 leading in practice from a battery (not shown).

The imbedding device is used as indicated in Fig. 1, the bar 10 being positioned so that two end pins 12 will contact with the wire. Inasmuch as the alternate pins are each in metallic contact with a separate conductor strip 11, the current will pass from one binding post through the adjacent strip 11 to the irst pin 12 connected with said strip, through the said pin, and return through the wire B and the second pin 12 in Contact with the wire, to the second binding post. At the same time the pins may be caused to exert a slight pressure on the wire to cause it to melt its way into the wax. Thus, the section of the wire B between the first two pins having been heated and imbedded, the current is cut oill from the wire B simply by rocking the bar 10 with the contact edge of the second pin 12 as ai center, until the third pin 12 which is the center pin in the example shown, is brought downward to a bearing on the wire B so that the current will now pass through that section of the wire B between the second and third pins. As the pins are gradually of less height from the center toward the opposite end from the lirst pin, the operation is continued by a further rocking of the bar l0 when the successive pins 12 contact with the wire to be imbedded.

The end pins 12 are bent outwardly at an angle as indicated at 16, whereby to bring their contact points close against the frame A so that the current will pass through the Wire outside of the foundation C and insure the heating of the outermost Walls of the latter.

Having thus described my invention I claim as new, and desire to secure b-y Let-V ters Patent:

1. A Wire ilnbedding device including a support, insulated conductor elements carried thereby and adapted for connection with a source of electricity, and a longitudinal series of contact elements extending from said conductor elements and projecting from said support to bear in pairs on successive sections of the Wire to cause the electric current to pass through the sections of the Wire in succession as the contact ele ments are brought in succession into contact With said Wire, said contact elements extending alternately from the respective conductor elements.

2. A Wire imbedding device including a bar, a longitudinal series of contact elements carried by said bar adapted to bear on the Wire to be imbedded and projecting from the bar to a progressively increasing extent from an end of the bar, so that rocking of the bar Will bring successive contact elements against the Wire, and conductor elements carried by the bar and adapted for connection with a source of electricity, said conductor elements being in connection respectively With alternate contact elements.

3. A Wire imbedding device including a support, a series of contact elements on the support and projecting therefrom to bear against the Wire to be imbedded, and ini sulated conductor elements on said support adapted to receive an electric current and connected alternately with alternate contact elements, said contact elements progressively increasing in height from both and elements to the center element.

4L. A Wire imbcdding device including a support, a series of contact elements on the support and projecting therefrom to bear against the Wire to be imbedded, an insulated conductor element on said support adapted to receive an electric current and connected alternately with alternate contact elements, said contact element-s progressively increasing in height from both end elements to the center element, and the end contact elements being sent outward at the free ends.
